Paddy Power exemplifies the Jack of All Trades in the UK online gambling scene. See if you agree by reading our short online casino reviews of each operator.

The best online casino will feature licensing from the UKGC, excellent responsible gambling measures in place, and SSL encryption to ensure your personal and financial information is safe. The second thing most players miss is that RTP is a theoretical figure calculated across hundreds of millions of simulated spins in a certified testing environment. The main reason is that casinos want to stop people claiming the same bonus multiple times. Wagering requirements below 20x, or offers with wager-free spins, are the only promo setups where you\u2019re a favourite to walk away a winner.<\/p>\n
